An Unconventional Computing Approach for Quantum Computer Control and Quantum Memory

This document proposes an “unconventional computing” technology for controlling quantum computers, including specific application to quantum memory based on posits. While improved qubits are a top priority in quantum computing, existing approaches for classical control systems
limit scale up to 50-1,000 qubits due to wiring between the cryogenic environment and room temperature or excessive (CV2) dissipation in cryogenic electronics.

Barrel Shifter Permutation Circuit, 2LAL and SCRL

To illustrate the concept of FET-only adiabatic permutation stages as described in ref. 1, these test circuits demonstrate both 2LAL and SCRL 4-bit barrel shifters implemented with FET-only permutation stages.
The circuits are in a test harness comprising a four- or five-stage shift register preloaded with data patterns 1, 2, 4, 8 and a shift count pattern of 3, 3, 3, 3 places. The files should be available wherever the reader obtained this document, but the main files have been pasted into the appendix of this document as a failsafe. The circuits are designed for ngspice version 30 and use the built-in BSIM 3.3.0 transistor model, with voltage sources to alter gate bias (which is not realistic)
